I've been teaching myself Objective-C and I wanted to start creating projects that don't use ARC to become better at memory management and learn how it all works. I've been attempting to build and run applications, but I'm not really sure where to start as modern iOS development is used with Swift and memory management is handled. Is there any way to create modern applications that use Objective-C, UIKit, and not use ARC?

I’m creating an app using SwiftUI, and I would like to incorporate a small Java codebase that I created for the Android version of the app. Is there a way to package the Java code to work on iOS and macOS

After swapping the -objectAtIndex: method using method_exchangeImplementations, it will cause continuous memory growth. Connect the iPhone and run the provided project. Continuously tap the iPhone screen. Observe Memory; it will keep growing. Sample code

Greetings! I am actively working on porting x64 code to Apple Silicon now that the time is nigh and part of the fundamentals of our software is a coroutine library for handling cooperative multitasking of GUI operations on the main thread. I was hoping to get the locations of the stack pointer and frame pointer in jmp_buf so, after setjmp() can redirect them to the primary handling routines in our coroutine library that handles the cooperative scheduling (which replaced and ported the old classic MP routines) which worked for PowerPC, i386 and x64. Any thoughts on where in the jmp_buf these might be located? I didn't see anything in the XNU open source. Any advice would be much obliged instead of having to dive in and re-implement these routines in assembly myself!

We developing Native App with C++17 for iOS. We override global new and delete operators. This App deallocate all allocated memories correctly by Run on Xcode (Command + R), but exception occurs launch from xcrun or App icon on iPhone. I debugged the exception. Overriding new operation was called correctly, but overriding delete operation was not called. The default delete was called. I'm not sure why is that. STEPS TO REPRODUCE Build xcode project. Run "xcrun devicectl device install app --device " Run "xcrun devicectl device process launch --console --device " PLATFORM AND VERSION iOS Development environment: Xcode 16.4, macOS macOS Sequoia 15.5 Run-time configuration: iOS 18.5 main.cpp I attached is sample code to reproduce this problem. main.cpp

I'm working on a cross-platform C# application that converts HTML content to PDF. The goal is to render dynamic HTML pages (including CSS and JavaScript) as high-quality, printable PDF files. Additionally, I need to support features like adding headers/footers, securing PDFs with passwords, and controlling user permissions. While everything works well on Windows, I need some help rendering consistency and handling permissions on MacOS.

I am using CHCSVParser in objective-c to use the CSVString extension of the Array instance method. When I installed a new app on iOS18.1.1, the correct value (@"Application,"abc,def"") was returned for both the first and second turns, but when I installed a new app on iOS18.2, the correct value was returned for the first turn, but @"" was returned for the second turn. Even when I debug with step into, I can enter the CSVString for the first turn, but I cannot enter it for the second turn and after. It's as if the instance method is not being generated. There are in-app purchases between the first and second turns, but the view controllers that are called are also the same. Is there any change between iOS18.1.1 and iOS18.2?

We are Java application developers and we have a question regarding camera access via WebRTC on iPadOS. Specifically, on iPadOS 17.1, we are encountering an issue when trying to access the camera via the WKWebView API in the Chrome browser, where an error occurs and the camera capture fails. Our investigation suggests that device access through the navigator.mediaDevices property via the WKWebView API may not work in Chrome. However, it works as expected in the Safari browser, leading us to wonder if this is a Chrome-specific limitation, or if it's due to an iPadOS setting or specification. At this point, we are unsure if this issue is related to the WKWebView and WebRTC specifications on iPadOS 17.1, or if there are specific limitations in Chrome. We would appreciate any insights or solutions regarding camera access in iPadOS 17.1 with WKWebView and WebRTC, especially in relation to Chrome.

Hello, I have a problem with Xcode, in C++ language. When I create a new project, I put my program in a file and click Build. It works correctly and without any problems, but when I enter a second file in the same project and click build, it says build failed. In the log it says, duplicate symbols appear.

We want to do below addition to iOS Mobile App. Airpod announces Push notification = which is workking now we want to use voice command that "Reply to this" and sending Reply to that notification but it is saying it is not supported in your app. So basically we need to use feature - Listen and respond to messages with AirPods Do we need to add any integration inside app for this or it will directly worked with Siri settings ? Is it possible to do in non messaging App? Is it possible to do without syncing contacts ?
